Abstract
La presente se refiere a un aparato (1) para el procesamiento de una señal de audio codificada (100) que comprende una pluralidad de señales de mezcla descendente (101) asociadas a una pluralidad de objetos de audio de entrada (111) y parámetros de objeto (E). El aparato (1) comprende aun agrupador (2) configurado para agrupar las señales de mezcla descendente (101) en grupos de señales de mezcla descendente (102) asociados a una serie de objetos de audio de entrada (111). El aparato (1) comprende un procesador (3) configurado para ejecutar por lo menos un paso de procesamiento individualmente en los parámetros de objeto (Eₖ) de cada serie de objetos de audio de entrada (111) a fin de emitir resultados de grupos (103, 104). Se presenta además un combinador (4) configurado para combinar dichos resultados de grupos (103, 104) o resultados de grupos procesados a fin de emitir una señal de audio decodificada (110). El agrupador (2) está configurado para agrupar las señales de mezcla descendente (101) de tal manera que cada objeto de audio de entrada (111) pertenezca sólo a una serie de objetos de audio de entrada (111). La presente se refiere asimismo a un método correspondiente.This refers to an apparatus (1) for processing an encoded audio signal (100) comprising a plurality of downstream mixing signals (101) associated with a plurality of input audio objects (111) and parameters of object (E). The apparatus (1) comprises a grouper (2) configured to group the down mix signals (101) into groups of down mix signals (102) associated with a series of input audio objects (111). The apparatus (1) comprises a processor (3) configured to execute at least one processing step individually in the object parameters (Eₖ) of each series of input audio objects (111) in order to output group results ( 103, 104). There is also a combiner (4) configured to combine said group results (103, 104) or processed group results in order to output a decoded audio signal (110). The grouper (2) is configured to group the down mix signals (101) such that each input audio object (111) belongs only to a series of input audio objects (111). This also refers to a corresponding method.
